Motorists are being warned the Mountain Road is set to shut for six days throughout December for surveying work to be carried out.
The Department of Infrastructure (DoI) is planning to close the major A18 route between Creg-ny-baa and Brandywell from 9.30am-4.30pm on December 2, 3, 9, 10, 16 and 17.
There are contingency dates in place for December 11 and 18 if adverse weather prevents the work taking place on the other dates.
The Victory Café will remain open during the road closures.
The surveying work will help the DoI determine what, if any, road improvements will be required for that stretch of the Mountain Road.
